Population response of phytophagous arthropods and natural enemies to toxaphene, based on its use as a herbicide (two applications at the dose of 3,36 kg of a.i./ha) to control sicklepod, Cassia obtusifolia, was studied on soybean Glycine max.(L.) Merrill, in a large field experiment of 0.04 ha parcels in a diversified agroecosystem at Madison Co., in North Florida, USA, during the 1980 crop reason. Only intensive toxaphene treatment appears to have affected population os Spissistilus festinus (Membracidae). Timing and intensive of sprays significantly decreased and increased the levels of the noctuid pests, Anticarsia gemmatalis and Heiothis zea, respectively. Poplations of the predators Nabis roseinennis (Nabidae), and Solenopsis invicta (Formicidae) decreased while larvae of Chrysona rufilabris (Chrysopidae) and Labidura riparia (Labiduridae) increased significantly following toxaphene applications. Populations of L. riparia augmented independently of the prey density of A. gemmatalis; however, nabids and geocorids showed a progressive and weak density dependent response to A. gemmatalis. Migratory activity of the predador Calosoma alternans was strongly associated with the presence of high levels of A. gemmatalis caterpillar populations. |
